Forget concentration curls. You cannot significantly change the shape of your biceps...BUT...you can "heighten" them, making them appear more peaked! To accomplish this you must hypertrophy your brachialis, which lies underneath the biceps. Thickening this muscle will "push" your biceps up higher. Here's how...
ROUTINE 1:
-90 degree preacher curl...2 x 4-6
-lying overhead cable curl...2 x 6-8
-incline hammer curl...2 x 8-10
ROUTINE 2:
-90 degree dumbell preacher curl...2 x 4-6
-seated overhead cable curl...2 x 6-8
-reverse curl...2 x 8-10
This will make mountains out of mowhills!
